Strikes delay 70 Qantas flights
Qantas Airways is delaying 70 flights amid another series of strikes by its ground workers.
The Australian airline said around 10,000 passengers would be affected by the strike by the Transport Workers Union.
Qantas has been grappling with months of strikes by unions representing aircraft mechanics, pilots, baggage handlers and caterers.
The unions are concerned that the airline plans to move jobs offshore and are also fighting for better pay and conditions.
Prime minister Julia Gillard has said the government will intervene if the strikes begin to threaten the national economy.
